MAC address vendor

Aculab PLC — registered prefix identified; device unknown

Primary prefix
00:02:1F
Block
MA-L

Summary

// what this is
Aculab is registered to MAC prefix 00:02:1F in the IEEE OUI database. When a device's MAC address begins with 00:02:1F, that block was registered by Aculab — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
A prefix match identifies the registry assignment and does not establish a specific device, deployment, current vendor identity, or security state.

About this vendor.

Updated  ·  Confidence: High  ·  2 sources  ·  How this page is checked

A MAC address beginning with 00:02:1F matches an IEEE MA-L assignment to Aculab PLC; the record does not identify a particular device or product. It establishes the registry name associated with the prefix, not the manufacturer of a captured device, its current owner, or its safety.

This 24-bit prefix leaves 24 bits for suffix values, or 16,777,216 possible values within the block. That is a mathematical address-space count, not a count of deployed devices or shipments. The prefix’s first octet is 00: its Group bit and Local bit are both zero. Those bits are fixed for an exact literal prefix match; changing either bit produces a different prefix.

RFC 7042 describes how 48-bit MAC identifiers use an organizational prefix followed by additional bits, and explains the Group and Local bits. The supplied IEEE CSV row has no assignment date. The retrieved material does not support assigning a device category, product, industry, or website to this legal entity.
